6 Claims.

This invention relates to disk plows "of the type employing means for raising and lowering the disks relative to the ground, for the purpose of adjustment and transportation.

This application is a division of the co-pending application to Alvah E. Rutter, Serial No. 504,427, filed September 30, 1943, now Patent 2,454,482, issued November 23, 1948.

An object of this invention is to provide an improved rock shaft bearing of novel constructlon.

Further objects will become apparent from the following description and accompanying drawings in which a satisfactory embodiment of the invention 'is shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention as herein expressed.

In the drawings,

Fig. 1 shows a plan view of a plow embracing the invention;

Fig. -2 shows a perspective view of the plow with parts removed;

Fig. 3 shows a left side View of a plow in working .position and withparts removed;

Fig. 4 shows a section at 4-4 of Fig. 3.

Pl'o'ws of this type usually comprise a frame l under which a disk gang II is journaled. A

forwardly-projecting frame-work I2 is secured to frame l0 and supports land wheel B, a front furrow or supporting wheel I4 and a rear furrow wheel l5. The gang II is journaled in a plurality of bearings l6, and brackets only one of each being shown. Wheels l3, l4, and 15 are arranged to be adjusted so that the gang may be raised or lowered. The means :of doing this is clear from the drawings, is described in Rutter Patent No. 2,454,482, and will be further described only so as to make the present invention clear.

Referring to Fig. 2, a cyclic clutch I8 is fixed on a crank arm l9, and,which serves to raise and lower the frame ID by means described in Patent No. 2,454,482 and which means is ar: ranged to simultaneously act upon all wheels |3, I4, and I through proper rock shafts and links not necessary to describe here.

This invention comprises an intermediate rock shaft 20 supported horizontally over frame I 2 (see Fig. 2). Rock shaft 20 is the central control member for raising and lowering the discs and comprises a horizontal bearing portion 2|, 2. generally downwardly extending arm 22 and a generally upwardly extending arm '23. A link 24 connects crank arm IS with arm 22.

The rock shaft 20 is journaled in a bearing 25, the axis of the former extending normally to frame In. Bearing 25 comprises a lower channel saddle member 26 formed semi-cylindrically as shown in Fig. 4 so as to provide a bearing surface for the lower portion of member 21. The force extended on the bearing surface is in a downward direction. Saddle member 26 is seecured by welding, or any suitable method, to frame |2 as shown in Figs. 2 and 3. Saddle member 26 has upwardly extending sides 2'! which terminate above the bearing portion 2| of rock shaft 20. A spacer and housing plate 28 fits intermediate the sides 21 and maintains the por- 'tion 2| of rock shaft 2|! in contact with the seat of saddle member '26, the last mentioned seat forming the bearing proper. Bolts 29 pass through holes provided in sides 21, and nuts 3!] serve to secure the plate 28 between the sides 2'! confining the portion 2| in the saddle 25 but allowing the portion 2| freedom to rotate. Ends 3| of plate 28 are formed to provide a channel for bolts 29 as shown in Figs. 3 and 4.

This construction provides a convenient and economical saddle bearing for use in positions where the load is in one direction, and facilitates assembly and disassembly.

The above being a complete description of an illustrative embodiment of the invention, what is claimed as new and desired to be secured by Letters Patent of the United States is:

1. In a disk plow having a frame and a power lift, a rock shaft construction for the power lift comprising a horiZontally-journaled rotatable ro'ck shaft, a bearing for said rock shaft secured to said frame and comprising a saddle formed to provide a bearing surface for the lower half of said rock shaft, said bearing surface co-extensive with degrees of the periphery of said rock shaft, said saddle having upwardly extending walls tangent to said rock shaft and extending above the latter, a housing plate intermediate said walls and arranged to confine said rock shaft substantially in contact with said bearing and a plurality of fastening members arranged to secure said walls in contact with the said housing plate, the latter making a line contact with said rock shaft at a point diametrically opposed to said bearing surface.

2. A journal bearing for a one-way load for use with a disk plow having a plurality of supporting wheels, a power lift and linkage leading from the power lift to one of said supporting wheels, said linkage including a rocking journal, the combination of a U-shaped channel element having a closed side constituting a saddle and embracing substantially one-half of the periphery of said journal and disposed in the direction of the force resulting from the one-way load and also having upwardly directed spaced walls tangent to said channel, spacer and cover means interposed between the walls and contacting said journal along a line on the periphery thereof and clamping means extending between the walls spaced from said closed side and adapted for urging said walls toward each other and clamping said cover means therebetweenfor predetermining the spacing of the walls and closing the opening to prevent inadvertent displacement of the journal therefrom.

3. In a disk plow having a plurality of supv porting wheels, a power lift and linkage leading from the power lift to one of said supporting wheels and including a rocking journal disposedto beforced in a predetermined direction, laterally of said journal by the actionof said linkage, a bearing for said journal which comprises a flexible saddle member supported on said plow and having a rounded closed portion adapted to fit one side of said journal and disposed in the direction .in which said journal is forced, and an open portion disposed in the direction opposite to that in which said journal is forced, upstanding sides defining said open portion, and a substantially flat plate disposed between said upstanding sides and presenting its edges thereto so as to determine the spacing between said sides and the fit of said saddle about said journal, and said plate having channel portions extending transversely of said journal, and

, bolts extending through said upstanding sides and through said channels and forcing said sides into clamped relation against the edges of said plate. 7

4. In a disk plow having a plurality of supporting from the power lift to one of said supporting wheels and including a rocking journal disposed to be forced in a predetermined direction, laterally of said journal by the action of said linkage, a bearing for said journal which comprises a flexible saddle member supported on said plow and having a rounded closed portion adapted to fit one side of said journal and disposed inth'e direction in which said journal is forced and contacting substantially 180 degrees of the periphery of said journal, and an open portion disposed in the direction opposite to that in which said journal is forced, upstanding sides defining said open portion, and a substantially flat plate disposed between said upstanding sides and presenting its edges thereto so as to determine the spacing between said sides and the fit of said wheels, a power lift and linkage leading.

4 saddle about said journal, and said plate having channel portions extending transversely of said journal, and bolts extending through said upstanding sides and through said channels and forcing said sides into clamping relation against the edges of said plate.
